To all whom it concern:

Be it known that 1, WILLIAM, H. CARPEN- TER, a citizen of the UnitedStates, residing at Bristol, in the county QfHartford. and State ofConnecticut, have invented certain new and useful Improvments in aMachine for Coiling Sheet Metal, of which the following is aspecification.

My invention relates to machines for coiling sheet metal and the objectsof my improvements are simplicity and economy in construction, andconvenience and efliciency in operation, particularly with reference toend a machine.

In the accompanying drawing :Figure 1 is a perspective view of mymachine, with the frame broken away showing the delivery end and part ofone side, the top-cover and a part of the housing for the ears beingremoved. Fig. 2 is an enlarged of a portion of the delivery end of themachine, together with a sheet of metal passing therethrough, andshowing that side of the machine that is out of view in F ig. 1.

The machine as shown is constructed on one end of the frame of amachine, for scouring and coiling sheet metal. I have herein shown thesub-frame and main frame as broken off so as to omit that part of themachine that contains the scourm devices. I have however retained thesha ts 33 and 34 of a pair of feed rolls, which, rolls delivered themetal after being scoured from the scouring devices to the coilingmachine. These feed rolls may be omitted and the metal may be deliveredto the machine from any suit able-mechanism, as for example a rollingmill, or the metal may be fed directly into the coiling rollers.

A, A, designate the two sides of the subframe or legs which areconnected together by suitable cross rods 5 and brace rods 6 in anyordinary-manner. The two sides B, B, of the main frame are placed on thetop of the sub-frame and secured thereto in any proper manner, as forexam 1e by the bolts 7. Mounted in the two sires B, B, of the main framethere is a set of three forming or coiling rollers, consisting of twolower rollers 36 and a centrally arranged up er roller 37. The roller 37is vertically a justable by means of sliding boxes 59 and ordinaryadjusting screws 60. These rollers are drisven coiling the metal into aroll at the delivery side elevation by the driving shaft 38 having agear 40 at one end, and a gear 41 at the op osite end for a purposehereinafter describet In Fig. 1 the shaft 38 is shown with room enoughto apply a driving pulley by the side of the gear 40 but the said pulleyis omitted from the drawing in order to'show the gearing. The gear toengages and drives gears 42 on the ends of the lower rollers 36, asshown in Fig. 1, while one of the gears 42 drives the upper roller 37 bymeans of the two idle or intermediate gears 43, and gear 44 fixed on theend of the said upper roller. the coiling rollers 3637 there are twolive rollers 45, that form a support for a coil or roll of metal. Theseare so geared that their upper surface travels in the same direction asthe opposing surfaces of the coiling rollers, that 1s towards thedelivery end of the machine. They are so driven by means of the gear 41on one of the rollers 36, which gear 41 engages anddrives theintermediate gear 46 for driving the gear 47 fixed on the end of one ofthe live rollers 45, while the same gear 41 on roller 36 also enga esand drives another intermediate gear 48 or drivin the gear 47 that isfixed on the end of the ot ler one of the live rollers 45, as shown inFig. 2. The gears shown in Fig. 2 are covered in Fig. 1 by the housing63.

Adjacent. to the coil supporting rollers there is a curved apron orguard 49 fixed on the frame and curving downwardly and out- A littleabove wardly towards the top of the C'Oll suvpportfi I ing rollers. Atthis end of the machine there is a cross bar 50 upon which is mounted apair of uides 51 extendingupwardly to and over tne upper side of thecoil supporting rollers. The lower ends of the guides 51 have heads oreyes 52 that are fitted to the cross bar so that they may be adjustedthereon to and from each other and hold in their adjusted position bymeans of the set screws 53. From the feed rollers on the shafts 33 and34, the metal-passes between the forming and coiling rollers which actto coil the metal into a roll. The metal 65, Fig. 2, comes out from thecoiling rollers,

, passes upwardly between the two guides 51 and is rolled into a coil orroll 66, shown, the said roll 66 resting on thc'coil supporting rollers45 which areso geared as to move in unison therewith. vAs the last endof the sheet comes through the coiling rollers the roll 56 is driven bythe live rollers 45 upon which the coil is supported and the loose endisdrawn up and the roll will continue to revolve on the rollers 45 untilthe operator is readyto remove it, and there is no danger of its fellingofi' or causing any inconvenience.

Vihile l have shown the coiling and coil supporting rollers in n machinefor scouring metal it evident that their construction and action wouldbe the same when placed at the delivery end of any machine for seting onsheet metal.

i claim as my invention:

1. In n machine for coiling sheet metal, the combination of a set ofcoiling rollers with a air of coil supporting rollers arranged pnrnlleto the coiling rollers in a horizontal plane and separated or spacedapart from each other above the said coiling rollers on onposite sidesof the central vertical plane t i I t 161 eoi.

2. In a machine for coiling sheet metal, the combination of a set ofcoiling rollers With a pair of coil supporting rollers arranged abovethe said coiling rollers, and connecting gearing for drivin the coilingrollers and coil supportingro ers in unison with each other.

3.- In a machine for coiling sheet metel, the combination of a. set ofcoiling rollers with a pair of coil sup orting rollers arranged abovethe said 00 ing rollers on o posite sides of the central Vertical planetiereof, and adjustable guides for the opposite edges of the metal, thesaid guides extending up Werdly from the delivery side of the coilingrollers over the top of the coil supporting rollers.
